FormFactor is trading 5.30% up at $107.09 after no clear company-specific catalyst was identified for the August 28, 2026 after-hours reversal.

  • Earlier regular-session weakness was attributed to broad semiconductor-equipment selling, with multiple peers declining.
  • No FormFactor-specific announcement was reported, and sector pressure does not clearly explain the after-hours gain.
  • The move may reflect repositioning or delayed trading activity, but confirmation is unavailable.
